Abstract:

Electronic voting has been widely used in modern democratic elections in recent years. Electronic voting has been a popular issue with cryptography technique because of the importance of voting results. There are many requirements for a secure electronic voting scheme. It is difficult for existing solutions to solve these incompatible requirements. Blockchain technology provides a new solution to electronic voting schemes. In this paper, we proposed an anonymous electronic voting scheme based on blockchain. This scheme effectively protects the privacy of voters. Unlike previously proposed blockchain electronic voting schemes, our scheme can be used in boardroom voting circumstances and allow voters to abstain from voting. More significantly, our scheme uses a blind signature and ring signature to eliminate “double-voting” behaviours. The results of the voting can be self-tallying by any nodes of our network because all ballots are stored in the blockchain bulletin board. At the end of this paper, we analyze our scheme with the requirements of a secure voting scheme.
